Re: migrating Hyper-V guest to KVM -- IDE controller

[Geoff Nordli]

Hi Mike.

I tried pre-installing the VirtIO driver using these steps.

https://platform9.com/blog/support/migrate-a-windows-vm-from-vsphere-to-kvm/

It didn't seem to help.   Though of course, I could have done something wrong. 

Through the Windows recovery console, I also tried adjusting the registry entries for IDE controllers which can cause the BSOD error message from this page: 

https://www.justandrew.net/2009/10/stop-0x0000007b-on-p2vd-windows-7.html

After a couple of days in the rabbit hole, I figured I would try to boot using vbox and the IDE controller, which worked. 

I won't be migrating any more VMs from Hyper-V so I don't need to figure it out.  Thankfully all of the other VMs I need to migrate are running vbox.  It is more of a question, if I have to do it in the future it would be easier if I could create an IDE drive.

If not, the post is here so people know to just boot with vbox first.

thanks,

Geoff

I am also pretty sure if you installed the VirtIO drivers first (if this is possible), you can then migrate the machine. If you can't boot windows to do that, the other alternative is booting VM with Windows ISO attached and VirtIO drivers boot floppy, and in Windows setup there is a way to open the registry of the Windows on the hard disk and tell it to install and load the drivers there.

Hi.

I am running KVM on Ubuntu 19.10.  The version is 4.0.

I need to get an IDE controller so I can boot the Windows guest on KVM.

IDE isn't an option in virt-manager.

When I try to use an IDE controller from the command line I get an

unsupported error message.  I have tried different machine types as well

(pc vs q35)

How would I get an IDE controller in KVM?

thanks,

Geoff

The generic sata controller doesn't work?

Which version of Windows are you using?

Hi Peter.

I am trying to migrate windows server 2008 R2.

No, the generic SATA controller didn't work.

When booting it gives you the BSOD with the 7B error code, which is boot 

drive inaccessible.

To migrate the machine I needed to boot the machine with VirtualBox with 

an IDE controller for the boot disk and an extra sata disk.  That seems 

to get the right SATA drivers installed. Then I can use KVM to boot it 

as a SATA disk.

thanks,

Geoff
